MANUFACTURE OF PANELED PAPZER.

SPECIFICATION forming part of Letters Patent No. 223,768, dated January 20,- 1880.

Application filed December 4, 1879.

To "all whom it may concern Be it known that we, JAMES B. SIPE and CHARLES ROGERS, of Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in the Manufacture of Paneled Paper and we do hereby declare the following to be a full, clear, and eXact description of the invention, such as will enable others skilled in the art to which it pertains to make and use it, reference being had to the accompanying drawings, which form part of this specifica tion, in which Figure 1 is a longitudinal section ofour machine. Fig.2 is an elevation, partly sectional, I

of the paneling-roll. Fig. 3 is a transverse section of same. Figs. 4 and 5 are respect ively a top and section view of the product, showing the thin center with thick edges. 1

This invention has reference to the manufacture of what we term paneled paper -a paper sheet or folio having a thin center or panel and thick edges-and includes both the machinery and the product of the same.

It consists in the construction, combination, and arrangement of devices, and in their product, substantially as hereinafter fully described and claimed.

The object is to produce a folio made up of a thin center, having edges of thicker stuff, the thick edgesi being on both faces of thethin center. 1

We accomplishthis by cutting a continuous lengthof the thick paper into panelsthat is, cutting outall the central partthen pasting a continuous piece of thin paper between two such paneled lengths, and then cutting the completed product into folios, as hereinafter shown.

To this end our invention is as follows: Though the various steps in the operation could be accomplished by separate mechanisms, we prefer to unite all into one co-operative whole, and to such will confine our description.

In suitable housings A we arrange two rolls, the lower roll,B, being preferably cylindrical andof soft material, such as annealed castiron, brass, or Babbitt metal. The upper roll, 0, is made adjustable to and from roll B by it is provided with knives suitably located.

We prefer the manner of constructing this roll shown, which is as follows: (See Fig. 2.) It is built in sections. The spindle a has a collar, b, forming one end of the roll. Next this is a steel knife, 0, projecting slightly out from the face of the roll. Then a thicker collar of steel, d, is set on, also having a knife-edge, as shown. Next is a long sleeve, e, forming the middle portion of the roll, and in longitudinal recesses in this, at the proper intervals, are

set the knives f and perforating-edge 9. At the end of the sleeve 0 is a steel collar, h, corresponding exactly to collar d. Beyond this a thin steel knife, 1, is set, corresponding to knife 0, and the Whole held in place by the collar 70 screwing on the spindle, or otherwise attached.

Knives 0 andi are continuous around the roll to cut the paper to a smooth and regular edge. Knives d and hare not continuous, be- 7 5 ing intended to cut the top and bottom of the panels only. Hence their cutting portions occupy only the distance between the knives f, which cut the sides of the panel. Of these there may be as many as desired, according to the size of the roll G. In the present instance we show two sets for cutting two distinct panels at one revolution.

In recessespassing around the roll, at appropriate points, we insert india-rubber rings or segments 1, Whose object is to gripe the paper and prevent its catching in the pass on account of slipping on the roll-faces.

Aroll of paper, being fed into the rolls B C, is

out as follows: Knives 0 and i trim the edges to the desired width, knives cl h cut the top and bottom of the panels, knivesf cut the sides of the panel, and perforating-blades g indent the strips between the panels,the result being that the paper comes out of the rolls paneled 5 and ready for cutting into such lengths as are desired.

In front of rolls B O are the rolls D E, each of which holds a roll of thick paper, and the end of each roll is passed on between the rolls 10o Q 223mm B 0, thereby causing two continuous sheets of panels to be cut simultaneously.

To facilitate the remaining operations it is necessary to provide some means of insuring the displacement of the pieces cut out in form ing the panels. Aframe,F,is1.)ivoted toasuitable point on the frame-work or housings, and has a downward extension, G, the whole forming a dropper, curved at its lower edge, so that when elevated it will not catch on the edges of the sheet. This is caused to rise and fall by pins or cams on one of the rolls B O, and is preferably so arranged as to fall upon the front edge of the panel asit emerges from the rolls. Immediately beneath its lower edge are two horizontal rolls, H l, geared to the rolls B O, or by any other means given the proper motion. A roll, J, is placed above roll I, the three rolls forming a triangle with a vertical and a horizontal pass.

As the sheets with their out panel emerge I from rolls B G the dropper F Gfalls upon the forward edge of the cut panel, forcing that edge downwardly into the rolls H I, which then draw it down and let it fall out of the way. The dropper rises in time to clear the uncut portion of the sheet, which passes on through the rolls H J. Here the two out sheets separate, one passing up over a friction-roll, K, and the other down under a fric- ,tion-roll, L. Between these two rollsis a sizing or paste boX, M, having a small roller, m, in its front portion.

Above the box M is a spindle, N, holding a roll of thin paper, as shown, whose end passes down into the paste-box and under roller m, receiving sizing or paste on both surfaces in its passage.

Emerging from the box M, scrapers may be applied to smooth off the coatings, after which the sheet passes onto a pair of pressure-rolls, -1 The paneled sheets converge to these rolls also, and the three sheets, the uncut sized or gummed sheet in the middle, pass through, and are united by pressure, after which they are passed off to dry. When dry they are cut to any desired length and used for any required purpose.

Roll I is provided with a yield-in g bearing, which keeps its face close against the face of roll H, so as to always bite upon the cut-out panels. Roll 0 is similarly journaled.

Though we prefer to indent the strip between the panels as a guide to their subsequent cutting, the perforating-knives forthis purpose may be dispensed with without departing from the essence of the invention.

What we claim, and desire to secure by Letters Patent, is as follows:

, l. The herein-described mode of making paneled paper, consisting in cutting the panels out of two lengths of paper, separating the two, sizing another length of uncut paper, and passing all three sheets between compressingsurfaces, substantially as described.

2. The herein'described mode of making paneled folios of paper, consisting in cutting the panels out of two lengths of paper, separating the two, sizing another length of uncut paper, passing all three sheets between compressing surfaces, and then dividing the lengths into paneled folios.

3. In paper-paneling machines, in combination with the panel-cutting rolls, a dropper arranged and operating substantially as described, whereby the cut panels are pushed out of the way.

4. The combination of the dropper and the horizontal rolls under it for carrying off the cut panel, substantially as set forth.

5. In paper-paneling machines, a cuttingroll having continuous knife-edges to cut the outer edge, segmental knives to cutthe top and bottom of the panel, and longitudinal knives to cut the side edges of the panel, in. combination with a pressure or anvil roll revolving therewith, substantially as specified.

6. In combination with the cutting-roll having the described knives for cutting one or more panels at one revolution, the perforatingedges g, arranged longitudinally of the roll between the knives f, substantially asdescrihed.

7. The combination of rolls B G, dropper F G, and rolls H I J, substantially as specified.

' 8. The combination of rolls B O, dropper F G, rolls H I J, rolls KL, box M, with its roller m, spindle N, and compression-rolls P, substantially as set forth.

9. As a new article of manufacture, paneled paper, consisting of a middle sheet of gnmmed paper having a continuous edge or frame of heavier paper pasted on both faces thereof, substantially as set forth.

10. The described blank, consisting of a continuous length of adhesive paper, having pasted on both faces thereof paneled lengths, the panels on both faces corresponding, the whole adapted to be severed at the strips separating the panels to form single folios or groups of the same.

In testimony that we claim the foregoing we have hereunto set our hands this 26th day of February, 1879.
